Examine the chemical equation and statement. Mg+2HCl⇌MgCl2+H2
The reaction is at equilibrium. The forward reaction is endothermic, and the reverse reaction is exothermic.
Given a decrease in temperature, how would the reaction shift?

a. A decrease in temperature will cause the reaction to shift toward the endothermic reaction, which has the reactants MgCl2 and H2.
b. A decrease in temperature will cause the reaction to shift toward the endothermic reaction, which has the reactants Mg and HCl.
c. A decrease in temperature will cause the reaction to shift toward the exothermic reaction, which has the reactants Mg and HCl.
d. A decrease in temperature will cause the reaction to shift toward the exothermic reaction, which has the reactants MgCl2 and H2.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
